GeForce RTX 2070 Super vs GeForce RTX 2080

Intro

Compare that to the GeForce RTX 2080, which features GPU core speed of 1515 MHz, and 8192 MB of GDDR6 memory set to run at 1750 MHz through a 256-bit bus. It also is comprised of 2944 Stream Processors, 184 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Both cards have exactly the same bandwidth, so theoretically they should have the same performance. (explain)

Texel Rate

The GeForce RTX 2080 should be a bit (approximately 9%) more effective at anisotropic filtering than the GeForce RTX 2070 Super. (explain)

GeForce RTX 2080		278760 Mtexels/sec
GeForce RTX 2070 Super		256800 Mtexels/sec
	Difference: 21960 (9%)

Pixel Rate

The GeForce RTX 2070 Super is just a bit (approximately 6%) faster with regards to FSAA than the GeForce RTX 2080, and also able to handle higher resolutions without slowing down too much. (explain)

GeForce RTX 2070 Super		102720 Mpixels/sec
GeForce RTX 2080		96960 Mpixels/sec
	Difference: 5760 (6%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (counted in megabytes per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
